Nat Med:研究揭示为何黑人冠心病患者存活率低于白人

2013-12-30 张笑 中国科学报

据《自然—医学》上的一项研究显示,与白人相比,黑人血液中血小板更容易被激活。由于血小板的激活会导致血液过度凝结,这项研究或有助于解释为何相比白人,冠心病黑人患者存活率较低。 Paul Bray等人对比了包括黑人和白人在内的154位健康人的血小板,发现黑人体内的血小板中的名为miR-376c的microRNA水平浓度低,这反过来导致其目标蛋白质数量较多。这种蛋白质又正好是凝血酶完全激活血小板所必需

Paul Bray等人对比了包括黑人和白人在内的154位健康人的血小板,发现黑人体内的血小板中的名为miR-376c的microRNA水平浓度低,这反过来导致其目标蛋白质数量较多。这种蛋白质又正好是凝血酶完全激活血小板所必需的。

这项发现突出了一个观点:在临床使用抗血栓类药物尤其是那些抑制凝血酶活性的药物时,要将种族差异因素考虑在内。
